None of the staff knew what was coming, or had even heard of a “Tip Bomb” when the two diners came in for lunch Friday afternoon and left Allis a $713 tip on a $16 bill – which is more than 4,000 percent.

Allis – who’s finishing up her last year at George Mason – plans to put the extra cash toward her future.

“Probably save it – I might spend a little bit but definitely going to put a lot of it towards school so I can get some of that paid off. I really appreciate it and I know there are a lot of other servers who deserve this and it just means a lot that I got it because I can really do a lot with that money and it just means a lot,” she said.
